Cover fastener



Nov. 2, 1937. P. L. BERKE COVER FASTENER Filed NOV. 19, 1936 ZINVENTOR. I

ATTORNEY.

Patented Nov. 2, 1937 Claims.

This invention relates to cover fasteners for receptacles, such as butter tubs, .or the like, and

has special reference to a fastener adapted for use on a receptacle and cover, the latter being provided with a metallic hoop or band thereabouts and projecting therebelow for cooperative overlapping engagement with a hoop about the upper edge of the receptacle.

The principal object of the instant invention is to provide a more efficient fastener and one i 'more readily applicable to the covered receptacle.

Another object is to provide a fastener having cooperative features engageable both with the hoop on the cover as well as with the hoop on the receptacle and directly engageable with the cover.

Still other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

Figure l is a sectional view of a fragmentary portion of a receptacle and cover thereupon, showing a spaced perspective view of a clip or fastener embodying the invention to illustrate their relative relation prior to the application of the fastener to the receptacle.

Figure 2 is a somewhat similar view showing the fastener as applied, and what may be ultimately done to augment its holding properties. i represents the upper edge of a fiber butter tub, having a wooden hoop 2 thereabouts, the upper edge of the hoop being approximately fiush with the upper edge of the tub when in its normal position thereupon. 3 represents the cover for the tub which is preferably of wood and having fixed thereabouts the thin metal hoop 4. This hoop 4 is preferably fastened as illustrated at 5 to the cover somewhatbelow the upper surface thereof and extending materially below the under face of the cover for overlapping engagement with the outer surface of the wooden hoop 2 of the tub, and upon which lower marginal edge this hoop is reinforced by the outwardly projecting arcuately shaped bead 6.

The clip, comprising the two major and minor parallel body portions 1 and 8 respectively which are offset as at 9, is shown in Figure 1 as spaced from the upper edge of the tub, and, in one respect, is deemed novel in that it is weakened as at ID at the point in the major portion thereof where the bend normally comes over the upper edge of the cover of the receptacle, so that it more readily assumes such position, and insures UNITED STATES PATENT OFFICE I COVER FASTENER Peter L.

uniformity of the bend in the clips when even more or less carelesslyapplied to the tub. This weakened portion may be, accomplished by a plurality of holespunched centrally therethrough, or by an arcuately shaped cutaway portion as illustrated in dotted lines at H.

The offset 9 is formed in the fastener at a point to register with the bead 6 in the cover of the receptacle when the clip is applied thereto; such application obviously necessitating the hooking under the bowl of the tub of the pointed upturned portion [2 at the lower end of the fastener, when it is seen by viewing Figure 2 of the drawing that this offset portion overlaps the bead 6, when, of course, the upper end of the major portion is bent over the edge of the cover and the nail carrying terminal of the clip struck with a hammer to force the nails into the cover '3 as clearly illustrated, and partially common in present practice. That is to say, it

is well known in the art that clips have been made carrying nails previously folded into a portion thereof, and also clips have been made for underlapping engagement of hoops about the receptacle.

Now that the clip is thus far described as being applied and shown in Figure 2 of the drawing, it will be noted that the minor portion 8 thereof is disposed upon an incline from the lower outer corner of the hoop 2 to the outer extremity of the bead 6, and this angular projection at times interferes with the proper functioning thereof, especially when many of these tubs are being quickly handled upon traveling belts or the like in loading or unloading of same when it becomes possible for such projection to become engaged with another object at which time the fastener might be rendered ineffective or materially loosened. Furthermore this projection, if fully appreciated at the time of its application to the tub, may function as a material advantage in that if it is struck with a hammer, as suggested in dotted lines at [3 it will be caused to hug the outer face of the hoop 2 as well as the bead 6 and thereby tend to shorten the length of the fastener and materially augment the downward pressure of the cover on the receptacle as well as increase the frictional contact of the bead portion of the hoop 4 about the upper edge of the hoop 2, and resulting also in a much smoother and neater appearing exterior of the tub and cover applied with such fasteners.

It will be noted that the upper edge of the hoop 2 is much narrower than the lower edge thereof, and that the lower beaded edge of the metallic band or hoop 4 is of shorter diameter than its upper edge, and the combination of this structure insures the hoop 4 hugging closely the outer surface of the hoop 2 and making a. snug fit of the cover on the tub.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. The combination with a receptacle having an encircling hoop about the upper open end thereof and a cover having a beaded hoop thereabouts for overlapping engagement with the first mentioned hoop, of a metal strip fastener for said cover characterized by being oifset intermediate of its ends for overlapping engagement with the bead of said cover hoop.

2. In combination a receptacle having a hoop about the upper open end thereof and flush therewith, a cover for said receptacle having a hoop thereabouts and projecting therebelow'for overlapping engagement with said first mentioned hoop and a metal clip for firmly holding said cover upon said receptacle and in contact with said first mentioned hoop.

3. In combination a receptacle having a hoop about the upper open end thereof and flush therewith, a cover for said receptacle having a hoop thereabouts and projecting therebelow for overlapping engagement with said first mentioned hoop and a metal clip for firmly holding said cover upon said receptacle and in contact with said first mentioned hoop, said clip having means whereby the holding tension thereof after being applied may be augmented.

4. The combination with a receptacle having a hoop about the upper open end thereof and a cover having a beaded hoop about the periphery thereof, of a cover fastener having means of engagement with the receptacle hoop, the beaded hoop,- and the cover.

5. The combination with a receptacle having a hoop about the upper open end thereof and a cover having a beaded hoop about the periphery thereof, of a cover fastener having a hooked portion at one end for engagement with the receptacle hoop, an offset portion for engagement about the beaded hoop, and holdfast means for engagement with the cover.
